Promoter Eddie Hearn believes featherweight Josh Warrington can become as popular as Ricky Hatton due to his fanatical support.
The 23-year-old won the European featherweight title with a fourth-round stoppage of Davide Dieli on Saturday night, adding to the British and Commonwealth titles he has won over recent months.
Bright future ahead
Speaking to Sky Sports after the fight, Hearn said: "We've got something major here."
"I've not seen anything like that. Belfast and Glasgow are wonderful cities, but you don't see a thousand people taking their shirts off and swinging them over their heads.
"This is the kind of support Ricky Hatton had back in those days, it's fanatical. It's not just 'let's go to Leeds and watch some boxing'. It's about one person, it's about Josh Warrington, it's a fanatical support and that means so much to someone's career."
Warrington - who sold 2,000 tickets himself for this fight - has a long way to go if he wants to emulate Hatton.
The Manchester fighter had a die-hard following with thousands crossing the Atlantic to support him during blockbuster fights against the likes of Floyd Mayweather and Manny Pacquiao.
Two-weight champion Hatton is one of the biggest names in british boxing history and Washington has the potential to follow in his footsteps.
World title fight in the future
Following his fourth round win in front of his home crowd in Leeds, Washington, who has a 100% record after 19 fights, winning three by knockout, is hot on the heels of the current world title contenders.
It has a been successful 12 months for Warrington, winning three titles and defeating two British rivals in Rendall Munroe and Martin Lindsay.
He will have Lee Selby firmly in his sights now and with the Welshman facing off against Joel Brunker on Saturday, it would edge Selby closer to a title shot.
With the Yorkshire fighter behind Selby in domestic rankings it could be the perfect fight for him as he continues his rise up the ladder, however Warrington has ambitiously targeted WBA title holder Nonito Donaire after his latest win.
